There's another rebate out for a free Oxy on-the-go acne stick, worth up to $8.99. You have until 10/31/17 to send in your rebate form, however your submission needs to be within 30 days of purchase. So don't pull a Goob and leave your form sitting in a to-do pile for months on end.
I'm so bad, I have to-do piles with lists of which other to-do piles to take care of first. Which reminds me, I should make a new Post-It reminder to get started on another to-do pile.
If Oxy isn't your preferred acne product, I also found a free $3/1 Neutrogena Acne Product coupon!
